Life on Earth may exist thanks to an incredible stroke of luck — a chemical sweet spot that most planets miss during their ...

As much as 45 oceans’ worth of hydrogen may be in Earth’s core, scientists reported, suggesting most of Earth’s water was ...

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

An experiment to quantify the amount of the universe’s lightest element in Earth’s core suggests that the planet’s water has mostly been here since the beginning ...

Earth’s habitability may trace back to a precise chemical balance during its formation, one that kept life-critical elements from disappearing into the core or drifting into space.

Parts of ancient Earth may have formed continents and recycled crust through subduction far earlier than previously thought.
